Another option is to use the "Return and landing at the starting point" function. If you use the button (Figure 4, no.
4) provided on the transmitter, the model will automatically return to the starting point and land there. There may be
very small deviations of 1 – 2 metres.
If you select this function, the model will first ascend to a safe altitude, return straight to the starting point, land there
and finally turn off the rotors.
Starting the rotors requires a takeoff site that is accessible in all directions. This function can therefore only
be used in large rooms/halls or outdoors. For safety reasons, the starting point must be at least two metres
away from people and objects.
However, this works only with enabled GPS and flawless GPS signal.
The automatic take-off and landing as well as the automatic return to the starting point are a permanently
programmed sequence. In order to ensure safe automatic landing of the model, it must be in a stable flight
state (hover) before pressing the corresponding control button on the transmitter, and the flight area or the
landing site must be at least two metres away from obstacles and people.
If this is not the case, the quadcopter may be damaged or may cause injury or damage to property!
Try to land as vertically as possible ("helicopter landing"). Avoid landing at high horizontal speeds ("aero
-
plane landing"). If you have not already done so, turn off the motors after landing.
Practice this start-up procedure a few times to get a feel for the quadcopter. Once you are reasonably confident, you
can start controlling the flight direction with the yaw, pitch, and roll functions (see notes in chapter 11). Always steer
slowly and carefully and practice the procedure a little before trying a new flight manoeuvre. The first few flights should
last no longer than 30 to 60 seconds each.
If you are already familiar with the flight characteristics of the model, you can do further exercises. Here you should
start with simple flight manoeuvres such as flying one metre forwards/backwards (pitch function). Then practice hover
-
ing left/right (roll function). If you have enough practice at this, you can start attempting to fly in circles and figures-
of-eight.
If you want to stop the flight operation, the rotors must be switched off after landing. Then flick the on/off switch on the
model into the "OFF" position (off = LEDs not lit). It is only afterwards that the transmitter can be turned off.
